代谢重编程是癌症的标志,已被证明在病毒感染中至关重要。代谢重编程为细胞提供大规模生物合成所需的能量和生物量。基于对有助于代谢重编程的细胞变化的研究,可以确定七个主要标志:(1)糖酵解和乳酸增加,(2)β-氨基醇分解增加,(3)戊糖磷酸途径增加,(4)线粒体变化,(5)脂质代谢增加,(6)氨基酸代谢变化,以及(7)其他生物合成和生物能量途径的变化。病毒依赖于代谢重编程来增加生物量,从而为病毒基因组复制和新病毒体的产生提供燃料。病毒利用代谢重编程的非代谢效应,创造抗凋亡环境并逃避免疫系统。其他非代谢效应可能会对细胞功能产生负面影响。了解代谢重编程在病毒发病机制中的作用可能会为抗病毒药物提供更好的治疗靶点。
Metabolic reprogramming is a hallmark of cancer and has proven to be critical in viral infections. Metabolic reprogramming provides the cell with energy and biomass for large-scale biosynthesis. Based on studies of the cellular changes that contribute to metabolic reprogramming, seven main hallmarks can be identified: (1) increased glycolysis and lactic acid, (2) increased glutaminolysis, (3) increased pentose phosphate pathway, (4) mitochondrial changes, (5) increased lipid metabolism, (6) changes in amino acid metabolism, and (7) changes in other biosynthetic and bioenergetic pathways. Viruses depend on metabolic reprogramming to increase biomass to fuel viral genome replication and production of new virions. Viruses take advantage of the non-metabolic effects of metabolic reprogramming, creating an anti-apoptotic environment and evading the immune system. Other non-metabolic effects can negatively affect cellular function. Understanding the role metabolic reprogramming plays in viral pathogenesis may provide better therapeutic targets for antivirals.
